The invention provides a system for sensing angular motion. The system includes a light source, a transducing member, and a modulating member havin g a track of translucent and opaque regions positioned between the light sourc e and the transducing member. The transducing member includes optical receiver s spaced across a width larger than or equal to three translucent and three opaque regions. The optical receivers, which may be interlaced across the transducing member, generate a plurality of output signals that form at leas t one output channel signal. The system may further include a second track of translucent and opaque regions and a second interlaced transducing member. T he second transducing member includes a second plurality of optical receivers arranged to generate a plurality of signals that may be used to generate at least one index signal.
